Definitions

• This invention relates to an additive or composition of marble adhesives, and more particularly to an additive capable of enhancing the toughness of marble adhesives.
• the bonding strength of an adhesive is jointly codetermined by the cohesive strength and adhesion strength of colloid. If the rigidity of the colloid is too strong, the interface for the bonding surface of the adhesive will be damaged; and if the toughness of the adhesive is too great, the cohesion for the bonding surface of the adhesive will be damaged. Therefore, the bonding strength of the adhesive will reach the optimum value only when the rigidity of the colloid is moderate. However, the rigidity of existing marble adhesives is relatively strong, and the bonding surface is easy to release after a long time, thereby damaging the interface and affecting the bonding effect.
• the craze of different degrees, appearing in the condensate of marble adhesives is common.
• the craze is very similar to the crack, and the difference is that the middle of the crack is hollow, while the middle cavity of the craze is connected by the craze material.
• the crack grows thickened and forms into the crack by fracturing the craze material. Due to the appearance and development of the craze, the mechanical properties of the material worsen rapidly.
• the "ice” phenomenon resulting from the volatilization and auto-agglutination of styrene (cross-linking agent and diluent) in the marble adhesives is common, thereby affecting the operation and use.
• a special adhesive is added to a marble adhesive, so as to improve the toughness of the conventional marble adhesive, restrain the formation of the craze, and maintain the good mechanical properties and strong bonding strength. Meanwhile, the adhesive avoids the "ice” phenomenon of the conventional marble adhesives, and reduces the cost of the marble adhesives.
• An additive capable of enhancing the roughness of a marble adhesive the additive being selected from the group consisting of R-(C 6 H 4 )-CH 3 OH, R-O-(CH 2 ) 2 -O-(CH 2 ) 2 -OH, R-O-CH 2 -CH(OH)-CH 3 , R-O-(CH 2 ) 2 -OH, or a mixture thereof, wherein, R represents hydrogen or an alkane, and a dosage of the additive accounts for between 0.5 wt. % and 10 wt. % of unsaturated polyester resins of the marble adhesive.
• the additive is benzyl alcohol, diethylene glycol methyl ether, diethylene glycol monoethyl ether, propylene glycol monomethyl ether, ethylene glycol monomethyl ether, or a mixture thereof.
• the dosage of the additive accounts for between 1 wt. % and 5 wt. % of unsaturated polyester resins of the marble adhesive.
• the dosage of the additive accounts for between 5 wt. % and 10 wt. % of unsaturated polyester resins of the marble adhesive.
• the dosage of the additive accounts for 8 wt. % of unsaturated polyester resins of the marble adhesive.
• the adhesive has the following advantages: 1. enhance the roughness of marble adhesive, improve the adhesion property of the bonding surface, and enhance the bonding strength of marble adhesive; 2. restrain the production of the craze, and improve the mechanical properties of marble adhesive; 3. reduce the viscosity of the colloid, optimize the harmonicity of the colloid, and improve the infiltration permeability of the colloid to the stone; 4. substitute a part of styrene, thereby restraining the volatilization of styrene (styrene, used as the reactive diluent by the current marble adhesive mostly, has strong volatility), and improve the "ice” phenomenon of the marble adhesive; 5. no pungent smell; and 6. reduce the production cost of the marble adhesive.
